Abstract
The ATLAS and CMS experiments carried out searches for invisible decays of the Higgs boson. The analyses have been performed in final states with missing energy in the transverse plane of the detector, in the case of typical signatures where the Higgs boson is produced in association with an electroweak vector boson or via gluon-gluon or vector boson fusion. Upper bounds on the production cross section of the Higgs boson times its invisible branching fraction have been derived depending on the assumed mass of the Higgs boson. Additional interpretations have been considered in the context of Higgs-portal models, which resulted in constraints on the production of Dark Matter candidates. The searches are based on the complete datasets from the Run-1 of the Large Hadron Collider, which includes proton-proton collision at a center-of-mass energy of √ s = 7 or 8TeV, with up to 20fb−1 of integrated luminosity.
